Is there a limit to what you can name your account? I imagine profanity is not permitted, I more mean, can only Administrators name themselves 'Doctor'/'Dr.'? I don't believe this is the case, but i wish to clarify.

No limit as long as its reasonable. Dr/Doctor is open to everyone, it's just another sort of name. Hell, most of the Senior Staff and admins don't even use it. As for changing your name, I'm pretty sure there's a way to do it. Might want to consult Wikidot's home page for that.

User names that involve the phrases 'SCP' or 'O5' or are otherwise inappropriate, will be denied out of hand.

This further makes me assume that, if you change your name to something containing one of these after joining, you will have your membership revoked. Other than that, knock yourself out. Doctor/Dr, Agent, and Mr are all fairly common. So is.. not having anything! Like me or Dmatix!
